What's the amount of RAM you have ?
Have you changed the default pool-size in the <zodb> section ?

Objet : [Zope] MemoryError that brings my zope to its knees


In the last month I have started to get these errors using Zope 2.7.7 in 
a ZEO configuration with one client and one storage server:

------
2005-09-12T23:46:07 ERROR(200) ZODB Couldn't load state for 0x055ba7
Traceback (most recent call last):
   File "/usr/local/Zope/lib/python/ZODB/Connection.py", line 600, in 
setstate
     self._set_ghost_state(obj, p)
   File "/usr/local/Zope/lib/python/ZODB/Connection.py", line 639, in 
_set_ghost_state
     state = unpickler.load()

142, in raising
     tb_text = ''.join(
MemoryError


Sometimes I see this too:

------
2005-09-06T15:23:30 ERROR(200) ZServer uncaptured python exception, 
closing channel <select-trigger (pipe) at bd9104c>

[/usr/local/lib/python2.3/asyncore.py|recv|342] 
[/usr/local/lib/python2.3/asyncore.py|recv|523])

And this one also brings the show down:

------

   File "/usr/local/Zope/lib/python/ZEO/zrpc/marshal.py", line 39, in decode
     return unpickler.load() # msgid, flags, name, args
MemoryError

It completely locks up the zope until I restart.  I added more RAM to 
the box and also bumped up the zeo cache-size to 100MB and 10000 objects 
in the zope.conf.  I also changed over from binding to an external 
ethernet interface and bound the zeo stuff to the localhost interface.

Any ideas on other things I could try?

Thanks,
Calvin
